Futaba Servos - BLS451

[mattr]

Right, managed to break a futaba BLS451 servo yesterday. Need some new bits.

Primarily the case.
The pin that holds the intermediate gear has moved and ground/gouged the hole in the top casing oval, its also bent (slightly).
Which box of spares does the pin come in on this servo?
I've not had any issues with it to date, so never had to order spares!

I have a vague suspicion that the pin is pressed into the top half of the case from new, can anyone confirm?
Or does it come in the bag of gears?
Cheers
Matt
